MailerQ previously published an article on this website in which we compared the features and the speed of MailerQ and a competing product, PowerMTA. The comparison was made using an unauthorized installation of a test version of PowerMTA and an unauthorized license without consent of Port25, the copyright-holder of the PowerMTA software. The conclusions of this test were therefore unreliable, not verifiable, and for these reasons false and misleading. This was wrong. We have removed the comparison page from our website and apologize to Port25 and anyone who reviewed the comparison page on our website.
